Return statements in functions returning bool should use true or false
instead of an integer value.

This code was detected with the help of Coccinelle.

Hi Gustavo,

I don't see this code in upstream tree. Is it against some other tree? Which?

Thanks

Yep. It's against linux-next.

Should I use [PATCH next] in the subject next time?

I dunno. I just find this part of kernel development process strange
and confusing. Say, how should testing of kernel patches work? Usually
today base commit is just captured by review system.
